Hepatic artery thrombosis following orthotopic liver transplantation:angiographic diagnosis and treatment.

Objective　To report the experience of diagnosis and treatment of hepatic artery thrombosis(HAT) following orthotopic liver transplantation.Methods　The clinical data of 34 orthotopic liver transplantation patients were reviewed.Diagnosis and results with different treatment methods were analyzed.Results　The incidence of HAT in our group was 8.8% (3/34).All of 3 cases of HAT were correctly identified by colour duplex ultrasonography.The first case , confirmed by autopsy, died of upper digestive tract bleeding on postoperative day 57.Other two cases were confirmed by hepatic artery angiography and then received interventional procedures with high dose of intraarterial urokinase;hepatic artery balloon angioplasty and intraarterial metallic stent was also performed.The patients died of sepsis and hepatic failure on postoperative day 18 and 65, respectively.All three recipients developed early acute rejections from the biopsy specimen before HAT was diagnosed.Conclusion　Interventional procedure is suitable for transient management of HAT and urgent revascularisation may obtain better results.
